The T40320 bolts to the T4 cylinder head and lifts at 22 1/2 degrees for installation & removal. The shackle can be moved to the forward hole position to lift the cylinder head level. The lifter comes with four T40130B captive M12 X 1.75 X 60MM bolts. This version requires the removal of the fuel injector. The T40320GC has a much higher pick-up position and does not require the injector toe be removed.
